Grounded In Reality: Better Ground Source Heat Pump Design

Why do ground loops in moist soils sometimes perform better than expected? What ground loop design tactics can address building system imbalance? Engineers need to take more responsibility for their full GSHP designs, and these questions are a good place to start.

With a little guidance on ground-source heat pump design temperatures and a few rules of thumb for ground loop flow rates, most engineers are pretty comfortable designing the building side of a ground-source heat pump (GSHP) system.

Geothermal Design: Code In Conflict?

Uniform Solar Energy and Hydronics Code (USEHC) contains some requirements that may be inappropriate given certain conditions, climates, or simple designer discretion. That’s not a problem … unless your locality or state adopts USECH language as binding. Dig into the problem and note a timely opportunity to avoid having these issues set in stone for another few years.
